HI, I'm learning how to use the BBB's PRU's, and I'm writing some assembly to utilize the PRU's integrated UART. I read through the PRU reference manual and used it to write my assembly code, but after running the code in a debugger, I'm getting almost no output. The only reaction from the PRU I could see with my logic analyzer is a small spike when the PRU writes a value to the UART output address, but it is not a valid UART communication.
Here's my assembly code <https://gist.github.com/winter-muted/4e4b113fb5767ea31fdae92f334af46a> and cape manager overlay <https://gist.github.com/winter-muted/6aea7bb9d05636a5304c93c202fbbf67> Any thoughts as to what might be going on?
